ADAM ODEL AND WILSON A. BURROWS, OF NEV YORK, N. Y. I

IMPROVEMENT IN LAMPS.

Specication forming part of Letters Patent N o. 33,447, dated October 8, 1861.

To all whom it may concern;

Be it known that We, ADAM ODEL and- W'ILSON A. BURROWS, of the city, county, and State of New York, have invented certain new and useful Improvements in Refiectors for Lamps, Lanterns, and for other Purposes; and we do herebydeclare the following to be a full description of the same.

The nature of our invention consists in adjusting on the gas-pipe or other illuminating fixture a conical reflector just below the jet of light and combining therewith a concave reflector placed above the burner, so that the ascending rays of light therefrom striking against it will be reflected `down upon the conical reflector, the sides of which being made at such an angle as to project the inipinging rays of light in horizontal lines. By this means the escaping ascending rays of light are utilized,and theentire volume of light is diffused in horizontal lines toillumine the surface of the earth, instead of part of it being dissipated in illuminating the heavens; but to describe our invention more particularly we will refer to the accompanying drawings, forming a part of this specification, the same letters of reference, wherever they occur, referring t0 like parts.

Figurel is a side elevation of the reflector. Fig. 2 is a vertical cut section of the same through the line x 05, Fig. Fig.` 3 is a plan view of the reflector.

Letter a is a representation of a gas-pipe having adjusted on it just below the burner a conical reflector b, which may be made of purposes.

metal, glass, or other suitable material, and of such angle of sides as desired. The adjust-ment of it on the pipe may be made by anj7 of the usual means known to the trade, or may be made so as to be removed, as occasion may require for reburnishing, Src. Above the jet of light is arranged on suitable rods c (or any other equivalent means) alconcave reflector CZ, of about the same diameter of the base of the conical reflector'. This concave reflector is made of metal, or may be made of glass prepared for reflecting Through the center of it is an aperture e, the object of which is to allow of the gas or smoke of the burner to escape and thereby prevent blurring` the surface of the reflector. It will be obvious that the curvature of thereilector may be made of"any radius desired.

The operation of the reflector is indicated by the dotted outlines, Fig. l.

Having new describedour invention and its operation, We will proceed to set forth what we claim and desire to secure by Letters Patent of the United `Statesflhe use of the combination of the burner or pipe a, conical reflector ZJ, and concave reflector (Z, and equivalents, when used for the same purposes herein before described and in like combinations. i
